Sec 7 T28N R35E
Structure: Shear Zone

Deposit: Broken ground cut by irregular tuff-bearing clastic dikes and veins of calcite containing crystals and coatings of cinnabar. Hanging wall, andesite. Stringers and small irregular aggregates of cinnabar are scattered in a matrix of quartz and calcite gangue.

Deposit type: Hot-spring Hg

Development: Eight claims. The original little linda claim was located in 1953 and in late 1954 and early 1955. The little linda 2-8 claims were staked by t.a. Cowan and m.g. White in 1953 a production of 11 flasks was recovered apparently from near-surface ore. In 1954-55, cowan mined in open cuts and through adits, constructed a 2-pipe retort, and reported production of an additional 6 flasks. Although he continued work until 1958, no additional production was recorded, but judging from the size of the dump, it seems likely that the mine has yielded more mercury than the records indicate. Ore was hand-sorted and processed in a retort 100 ft s. Of the lower portal. Nevada almaden property was developed by w.g adamson prior to 1909.
